<h1 class="title">Clear Kernel Build Error? Fix It</h1>
<p>
when I compile <a href="https://github.com/gentoobr/overlay/tree/master/sys-kernel/clear-sources">Clear</a> kernel with LLVM enabled, I got this error:<br />
</p>
<div class="org-src-container">

<p>
it's obvious that the <a href="https://github.com/clearlinux-pkgs/linux/blob/main/0128-itmt_epb-use-epb-to-scale-itmt.patch">sched_set_itmt_power_ratio</a> function is undeclared<br />
so I added the following like the function on top of it<br />
and it is able to compile :)<br />
